Authors: Aaron J. Gassmann (Iowa State University) , Ben Brenizer (Iowa State University)

Abstract

The purpose of this study was to evaluate the effectiveness of Bt corn targeting corn rootworm and soil insecticide, either alone or in combination, for management of larval corn rootworm injury. The Bt trait packages evaluated in this study were DeKalb Smartstax RIB, Pioneer AcreMax Xtreme (AMXT), and Syngenta Duracade. One soil-applied insecticide, Aztec HC, also was evaluated.
